SD818-Ⅰ(卡松1.5%)

 
結  構  式
   
 

物化性質

  組成:不含甲醛的各種異噻唑啉酮水溶液
  外觀:透明液體,淡黃色或淡綠色,無氣味
 
用         途
  适用于洗發香波、護發素、浴液等各類化妝品及日用清潔用品中
 
規         格
  異噻唑啉酮分析(HPLC) (1.5±0.05)%
  密度(20℃) 1.18-1.22g/cm3
  PH值 2-5
  色澤gardner ≤5
 
貯         存
  如果正确貯存并且保存在最初密封的包裝中,在室溫下,保質期為1年;
  本産品應放置于通風,清潔,避光,室溫的場所。
 
應         用
  用光譜測定其活性,在水中穩定性較好,低毒。SD818-1是一種多用途防腐劑。
  SD818-1的活性光譜圖覆蓋了細菌,包括甲醛殘留物、菌類、酵母和藻類等。
  SD818-1可以在生産過程中任何階段加入,但最好還是先加入進料液中。如果生産過程中溫度大于70℃,PH大于9,就需要在最後加入。為了保護産品要注意均一地加入防腐劑。因其粘度較低,SD818-1可以不經稀釋使用,當然也可以用水稀釋後再使用。
 

建議添加量:0.02-0.1%
PH适用範圍:1.0-8.0
使用溫度:<60℃

  将SD818-1應用在新産品中或是有新的應用時,預先建立複雜的測試系統是十分有必要的。

Chemical and physical data

  Composition:Aqueous, ormaldehyde-free formulation of various isothiazolinones
  Description:Clear, light yellow to pale green, almost odourless liquid
 
User
  For the preservation of aqueous coatings, polymer dispersions, filler suspensions, solutions and dispersions of adhesives and thickeners, concrete additives, oil emulsions, polishes etc.
For the preservation of surfactants, cleaners and disinfectants.
 
Specification
  (HPLC): (1.5±0.05)%
 
Storage
  If correctly stored and kept in the original sealed package at room temperature the shelf life is 1 year.
  The product should be protected from heat(temperature should not exceed 40℃)and from frost.
 
Applications
  With its broad spectrum of activity, good solubility in water and low acute toxicity, Preventol D 7 is a versatile preservative which is easy to use.
  Preventol D 7’s spectrum of activity covers bacteria, including formaldehyde-resistant species, fungi, yeast and algae.
  Preventol D 7 can be incorporated at any stage of the production process but is best added to the feedwater first. If higher Temperatures(>40℃)or pH(>9) Values are likely to occur during the manufacturing process, the product should be added at the end of the process, however. In this case take care to homogeneously distribute the preservative within the product to be protected. Because of its low viscosity, Preventol D 7 can be used undiluted or with water added.
 

The product can also be pre-dissolved in alcohols or alcohol/water mixtures. The use of Preventol D 7 in the preservation of aqueous formulations does not generally cause any undesirable side-effects. In contrast to preservatives containing active ingredients which split off formaldehyde, Preventol D 7 is highly suitable for the preservation of products which contain protein (e.g.casein).

  It is advisable to carry out compatibility tests before Preventol D 7 is used in new products or applications.
